It was 8:30 at night. Don was driving home. He was surprised when he saw a large, green light in the sky. The light was floating(漂浮)over a field. Don stopped his car and went out. He stood behind a tree and watched.
The light got very bright. It came nearer and nearer. It was a UFO! And it landed in the field!
"What's that? Maybe there are travelers from space in the UFO, "he thought. He started to walk across the field.
Then a large door on the UFO opened. Something came out! It moved toward Don.
The thing was not nice to look at! It had long yellow strings(细绳)on its face. Two round and blue balls were on its face. Under the round things, there were three holes. One hole opened and closed and made big noises.
Now Don was afraid, but he tried to be brave. He walked nearer and listened to the terrible noises.
"Hello," said the strange thing. "My name is Zeeb. I'm from the planet Mars(火星). This is my first trip to the earth. Glad to meet you."
